Does Reflective Window Film Reduce Heat?

Use window film to reduce excess heat build up in the home and workplace.

Reflective window film from The Window Film Company reduces heat by rejecting a percentage of solar energy (heat) before it can enter premises. Applied directly to glass, window film can be more effective at reducing heat than curtains or blinds.

How Does Reflective Window Film Work?

Reflective window film is typically applied to the internal face of the glass, with external-grade solar control films available where internal installation is not possible. Once installed, the film works immediately by reflecting a percentage of the sun’s solar energy away from the glass, reducing heat build-up inside the property. The level of heat rejection depends on the type of solar control window film selected.

Because reflective window film blocks heat before it enters the room, it is far more effective than blinds or curtains, which sit behind the glass and still allow solar energy to pass through.

Will Reflective Window Film Make My Property Cold?

No. Solar control window film is designed to regulate temperature, not eliminate warmth. It rejects excess solar heat rather than all heat, helping maintain a comfortable indoor environment without making rooms feel cold.

Will Window Film Make It Dark Inside?

Heat reduction window film will slightly change the appearance of your glass but will not significantly reduce natural light. Often compared to a very light pair of sunglasses, the film allows high levels of daylight to pass through while still delivering effective solar control.
